Hello again.
As I tried to explain to you, the note about the personal contact form is not
related to this issue, it only refers to whether somebody can privately write
to you through your user page (with an additional "contact" tab appearing to
the right) or not.
No admin is using this contact form to write to you or to expose your e-mail
address. The trisquel-users forums have always been synchronized to the
mailing lists and this topic has been addressed several times through the
years, like in 2012 (when we edited the e-mail field description to reflect
this) and several times later, like you can see at this long-standing issue (
https://trisquel.info/en/issues/2003 ).
I agree though that the help text describing the behaviour of the private
contact form can be misleading so I will be editing it to reflect this issue
the same as the one where you provide your e-mail address to create the
account.
